Cells are the smallest unit of life and the building blocks for all organisms. Each component of a cell has its own function. Animal and plant cells differ and they have similarities. Nucleus, cell ...

It’s a familiar image, reprinted in countless biology textbooks: an illustration of a typical cell, halved like a grapefruit to reveal its innards. Strands of endoplasmic reticulum encircle a nucleus ...

In living cells, regulation of the electrochemical environment is supposed to be managed by ion channels—protein complexes that reside in cell membranes and assume definite shapes. So, it’s surprising ...

An international team of researchers has created the most detailed model yet of how cells regulate traffic through the nuclear pore complex—the gateway between a cell’s nucleus and its cytoplasm. The ...

Sister cells are a pair of cells that share the same mother cell. In a new study published in Developmental Cell, researchers led by Université de Montréal (UdeM) professor Greg FitzHarris show how ...

Our body receives and processes a vast number of signals. Chemical signals serve as guidance cues and ensure, for example, ...

Which cellular processes ensure that immune responses are controlled precisely? A new study by the Institute of Cell Biology and Immunology Thurgau (BITG) and the University of Konstanz decodes a ...

All living organisms are made of cells, which are the smallest unit of life. Plants and animals have up to trillions of cells that work together to produce ever more intricate organization and ...

Cells are not isolated units; they continuously exchange proteins, genetic material, and even entire organelles with their neighbors. Intercellular transfer influences how tissues develop, respond to ...
